CHAEN Application led June 30,

To @ZZ whom t may concern.

Be it lrnown that l, Gnonen GARTLING, a citizen ot the United tates7 residing at Los Angeles, in the county ot Los Angeles and State ot alitorniay have invented a new and useful Chain Pump, ot which the followingn is a specification. c

rllhis invention relates to valveless chain pumps and it may be said to consist in the provision of the new and novel features and in the improved construction, combination and arrangement ot parts, the purposes of which will be apparent to those skilled in the art from a consideration ot the preferred term ot apparatus herein shown, described and claimed.

rlhis chain pump is similar in construction and operation to the cable pump described in my application for Letters-latent on cable pump, filed flug. 18, 1919, Seria-l Number 318,5;01, in that the inverted cone shaped shoe obstructs the passage ot large rocks or gravel from entering the pumpl cylinder.

@ne ot the principal objects oi this invention is to provide an endless chain pump that will be especially etlective in operation, cheapness or" construction, easily assembled and repaired and which will be exceptionally strong and durable.

Another object Ot the invention is to provide an endless chain pump that is especially adapted tor operation in wells having mud or hard sand therein as means are provided tor practically eliminating the wearing action of these substances on the movable contacting parts ot the pump.

lnother object ot this invention is to provide a chain pump with buckets that are of less diameter than the main portion of the pump pipe so that the buckets in the endless chain will contact only with the wall t t-he suction barrel.

Another feature of this invention is shown in the novel construction ot the buckets that are formed without packing that is common in bucket construction.

Another novel feature is shown in the means for mounting` the driving` shai't; and

also the means connected therewith for increasing or decreasing' the tension 0n the pump chain.

@ther objects7 features and advantages of the invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

The drawing; illustrates the invention.

F 1l is another enlarged view of a bucket and lchain attachment; also showing the pump cylinder by dotted lines.

Fig. 5 is an enlarged plan view of one of the buckets detached trom the endless chain.

ln detail the chain pump l has at its up per end the hollow stand Qthat is secured by the anchor bolts 23 to the cement platform 4.

ln one side of the stand 2 there is an opening; through which there is extended the spout n that is integral with the upper end of the pump pipe 7. v

, The spout 6 and pump pipe 7 can be held in place relative to the stand 2 and opening 5 by any well known means. As herein shown the pipe 7 has oppositely extending flanges 8 and 9 that are secured by the bolts 1G to the stand 2.

rllhe upper end ot the stand 2 has thereon the extension 11 to which is secured 90 by the bolts 12 the top covering 13; and central in the covering 13 is the hole 1a through which hole there is extended the bolt 15. The bolt 15 has its lower end integral with the cylinc rical bearing,- block 16, 95 which block is slidably mounted in the stand 2.

The bolt 15 is threaded and has attached thereto the nut 17 by which nut and bolt the bearing block 16 is raised or lowered in the stand 2.

' To the lower end of the bearing block 16 there are secured by the straps 18 the bushings 19, which bushings extend beyond the periphery ol the block 16 and through the slots 20 and 21 in the wall ot the stand 2; and in the bushings 19 there is 'loosely mounted the shaft 22.- To one end 'ot the shaft 22 there is secured the pulley 23 which pulley is driven from some source of power not shown. By means oi .the extension ot the bushings 19 into the slots 2O the shaft 22 isprevented .from turning and contacting with the sides of the slots 2O when power is applied to the pulley 23.

Secured about midway of the shaft 22 is the sprocket wheel 24 which wheel is adapted" to drive the endless chain 25.

The chain 25 is mounted on the sprocket wheel 24 and also on the sprocket wheel 26 that is mounted on the shaft 27 at the bottom end of the pump. The shaft 27 has its bearings in the walls of the shoe 28, one of which bearings is shown by dotted lines in Fig. 1. These bearings are ot common construction and are not shown in detail.

vThe shoe 28 is ot slightly less diameter than the inside diameter of the well casing 29; or so that the shoe 28 can be passed into the well casing 29 in a sliding lit when placed in pumping position.

The lower end of thev shoe 28 has the wall 1n thereof converging into an inverted cone 30 in which are a plurality of small holes 31; which openings give a tree passage to the water, but obstructs the passage of large rocks or gravel to the pump cylinder.

The upper end ot the shoe 28 is open for the purpose of providing a downward passage ot the chain 25 except that at one side ot the cylinder the wall is contracted into a threaded stem 32 to which stem is secured the lower end of the pump cylinder 33 and the openingv through the stem 32 is substantially the diameter of the opening through the suction barrel.

The upper end of the suction barrel 33 is detachably secured to the lower end of the pipe7 and as is seen in Fig. 1 the diameter of the pipe 7 is greater than the diameter of the suction barrel 33; the purposes of which will be hereafter explained.

rlhe buckets 34 are disks that are formed with a spherical periphery; that is the disks are the contour ot a sphere with opposite portions cut away.

1n Fig, 4 the outline and radius of the sphere are indicated by the dotted lines; and' as seen therein the periphery of the disk lies within the periphery of an imaginary sphere; also as seen in the drawing` the oppositely disposed flanges 35 and 36 have a portion of their outer surfaces lying within the outline of the sphere.

The purposes of the flanges 35 and 36 are to guide the disks or buckets 34 as they enter' the opening through the stem 32 and to keep the buckets from binding as they travel through suction barrel.

From the ioregoimgl it can readily be seen that only a small portion of the periphery of the disks or buckets 34 contact with the wall ot the suction barrel 33; and also that these buckets never contact with the pipe 7, consequently the i'rictional engagement ot the buckets with the pump wall is reduced to a minimum. Also the spherical periphery ot the disks prevent. sand or mud trom accumulating on the rim of the disk as they pass under the wheel 26 and approach the opening through the suction barrel.

There are cast integral with the disks 34 the chain link connections 37 and 38 which parts are adapted to join the links ot an ordinary sprocket chain; by means ot which connections the disks are easily and quickly secured in place or removed i'or replacing when too badly worn to perform their function.

The suction barrel 33 and also the disks 34 are case hardened steely so that they will resist the wear oi tine sand.

1t is intended however' that the suction barrel is a greater hardness than the disk as the latter are easily removed tor replac- 0. a. v n l l The real litt oit the water 39 1s in the suction barrel 33 in which the periphery of the disks 34 snugly contact with the inner wall oi the suction barrel; and the disks 34 are attached to the chain 25 at predetermined distances so that always one or more of them are within the suction barrel. 1n other words before the disk or bucket a has passed out ot the suction barrel 33 the bucket will enter.

While it is true that the real litt ot the water 39 is primarily accomplished by the buckets in the suction barrel 33 the other buckets also perform a lifting function; tor as water is non-compressible and as the space below each bucket from the pump cyliuder to the top spout is iilled with water when the pump is in operation the water cannot escape through the clearance between the buckets and the wall ot pipe 7, but must travel upward with the buckets so that the litt is distributed and not thrown entirely on the buckets in the suction barrel; and also the wear on the buckets is thereby limited to their short movementthrough the pump cylinder.

rlfhe sproclret` wheels 24 and 26 have the usual cutaway portions 40 and 41 to make a1 clearance tor the buckets 34.

By means oit the bolt 15 and nut 17 the bearing block 16 can be lowered to loosen chain 25 when old worn buckets are to be replaced with new ones; and also that parts be returned to operating position.

ln operation the pump l is placed in po sition as heretofore described and power applied to the pulley E23 to rotate the sprocket wheel 2li in the direction of the arrow shown in Fig. l; which rotation of the pulley will move the chain 25 and its associate-u parts to lift the water from the bottom of the well through the suction barrel and pipe 7 to the top of the pump where the water will discharge by gravity from the pump spout.

While l have described my apparatus as operating with a chain l do not wish to be limited to any specific connection between the buckets, as a cable or other connection can be used equally well.
